What Are The Advantages & Characteristics Of CNC Machining | CNCLATHING

1. High precision

(1) The structure of CNC machine has high rigidity and thermal stability, and measures to reduce the error are taken. With the error can also be compensated by the numerical control device, so CNC machine has higher machining accuracy.

(2) The transmission system of CNC machine adopts ball screw without clearance, rolling guide, zero clearance gear mechanism, which greatly improves the transmission stiffness, transmission accuracy and repetition accuracy of the machine tool. Advanced CNC machine adopts linear motor technology, so that the mechanical transmission error of the machine is zero.

(3) The error compensation function of CNC system eliminates the system error.

(4) CNC machine is automatic processing, eliminate human error, improve the consistency of the same batch of parts processing size, processing quality is stable. One time installation can carry out continuous processing of multiple processes, reducing the installation error.

2. Be able to process complex parts

CNC machine with more than two axes linkage can process the parts with curve generatrix, cam and various complex space curved surface, and can complete the processing difficult to be completed by ordinary machine tools. For example, marine propeller is a complex part with curved surface, which can only be machined by end milling cutter and five axis linkage horizontal CNC machine.

3. High productivity

(1) Save auxiliary time. CNC machines are equipped with automatic tool changing mechanisms such as turret and tool magazine. Manipulator can automatically load and unload tools and workpieces, greatly saving auxiliary time. No inspection is needed in the production process to save inspection time. When the CNC machining parts change, in addition to re clamping the workpiece and changing the tool, only need to change the program, save the preparation and adjustment time. Compared with ordinary machine, the productivity of CNC machine can be increased by 2 ~ 3 times, and the productivity of CNC machining center can be increased by more than ten times to dozens of times.

(2) Increase feed rate. CNC machine can effectively save the time of maneuver, move quickly, shorten the time of empty stroke, and have a large range of feed. It can effectively select reasonable cutting parameters.

(3) High speed cutting is adopted. In order to improve the cutting efficiency, small diameter tool, small cutting depth, small cutting width and fast multiple feed are used in CNC machining. The cutting force of high speed machining is greatly reduced, and the required spindle torque is correspondingly reduced. The deformation of the workpiece is also small. High speed cutting not only improves productivity, but also improves machining accuracy and reduces surface roughness.
